Determine current project path Ms Access

Hi,
I have been using the following code for some time to allow me to transfer data to an upgraded version of the database. See code snippet 1 below.

Basically it determines the existing Desktop file path.

I now want to change it to all me to transfer the data to a DB in the same folder as the open DB. I have the following code that seems to work, I just need to know if there are any issues I should consider that I have not in the code below.

Do I really need the following part.....

If Dir$(sUpgradePath, vbDirectory) = "" Then
sUpgradePath = Environ("UserProfile") & "\Desktop\" 'For use with Vista/Win7
End If

Is there any possibility that Access just would not be able to work out the directory path ?

Any advice would be greatly appreciated.

Using Environ() will work in some situations and not in others. It depends how the network / login scrips have been set up and also on the Office security settings.

My suggestion is to use the API that retunrs those special folders.

Using the attached code the desktop folder is returned by

GetSpecialFolder(&H10)

'
' Declares for Shell Items

Private Type SHITEMID
    cb As Long
    abID As Byte
End Type
'

    MKID As SHITEMID

' to the GetSpecialFolder Path routine

Public Enum fldrIDs
    fldrPrograms = &H2
    fldrControls = &H3
    fldrPrinters = &H4
    fldrPersonal = &H5
    fldrFavorites = &H6
    fldrStartup = &H7
    fldrRecent = &H8
    fldrSendTo = &H9
    fldrBitBucket = &HA
    fldrStartMenu = &HB
    fldrDeskTopDir = &H10
    fldrDrives = &H11
    fldrNetWork = &H12

    lRet = SHGetSpecialFolderLocation(0, CsIdl, IDL)

Hi,

I just realized that I should reorder the sequence as follows. Any other suggestions ???

Kev

'Determine current path
    sUpgradePath = CurrentProject.path
    
   If Dir$(sUpgradePath, vbDirectory) = "" Then
        sUpgradePath = Environ("UserProfile") & "\Desktop\"             
   End If
    
	'Check for terminating backslash sUpgradePath filepath.
    If Right(sUpgradePath, 1) <> "\" Then
       sUpgradePath = sUpgradePath & "\"
    End If
           
    sUpgradePath = sUpgradePath & DLookup("SysUpgradeTitle", "systblVersion", "")
